A perfluorinated all-conjugated copolymer, synthesized by a optimized Suzuki cross-coupling, displays blue-shifted absorption and emission spectra and simultaneously improved oxidative stability with respect to standard polyfluorene. Pure deep blue 405 nm electroluminescence with CIEy = 0.06 and remarkable 5.03 % external quantum efficiency is obtained in a optimized device architecture.

Abstract
A perfluorinated all-conjugated copolymer, synthesized by a optimized Suzuki cross-coupling, displays blue-shifted absorption and emission spectra and simultaneously improved oxidative stability with respect to standard polyfluorene. Pure deep blue 405 nm electroluminescence with CIEy = 0.06 and remarkable 5.03 % external quantum efficiency is obtained in a optimized device architecture.File in questo prodotto:
